JIC fittings are dimensionally identical to AN (Army-Navy) fittings, but are produced to less exacting tolerances and are generally less costly. SAE 45-degree flare fittings are similar in appearance, but are not interchangeable, though dash sizes 2, 3, 4, 5, 8, 10, 14, and 16 share the same thread size.

Is SAE 37 same as JIC?

The most common flare fitting standards in use today are the 45° SAE style, and the 37° AN style, also used with the JIC system. The AN / JIC style generally has a higher pressure rating for a given size tubing. SAE and AN/JIC fittings are completely incompatible due to the different flare angle.

Are SAE and JIC fittings interchangeable?

JIC Steps In

The majority of the hydraulic population agrees, the JIC (or SAE) 37 degree fittings are generally interchangeable with AN fittings.

What does JIC stand for in fittings?

JIC (or Joint Industry Council) fittings, defined by SAE J514, are compression fittings machined with a 37 degree flare seating surface and parallel threads. They are commonly manufactured in nickel alloys, brass, carbon & stainless steel.

What are SAE hydraulic fittings?

SAE(SAE J512)stands for the Society of Automotive Engineers. SAE fittings are mostly used in refrigeration, automotive piping systems and other low-pressure applications. It's common for copper tubes to be used with SAE threads. SAE Flare The SAE male and female halves both have a 45° flare seat.

Identifying JIC Fittings and Differences Between Flared Adaptors-JIS, SAE, Komatsu, BSPP (Flare)

What is SAE thread type?

SAE - Society of Automotive Engineers - straight threads are able to seal because of the 90-durometer Buna-N “O” Ring. This is a highly reliable and reusable thread type.

What is SAE port?

A threaded hole and stud system that may be used to attach fittings to a component or manifold. Sealed with an o-ring or gasket.

What is the difference between SAE and NPT?

What's the difference between SAE & NPT threads? The biggest difference is SAE is a straight thread, it needs additional O-ring, gasket or sealing surface to form a seal; NPT thread is a taper thread, it can form a seal using its thread pitch.

Is JIC the same as NPT?

JIC fittings is absolute different seal, not interchangeable. JIC hydraulic fittings is used in high pressure system, NPT fittings is used in low-pressure system. NPT pipe threads have always been popular, as leaks can be fixed by simply tightening the fitting.

How do I know if I have a JIC fitting?

4.Identifying the thread by gauge

In a word,if the fittings has a 37° flare (sealing surface angle)and straight United National Fine straight Threads (UNF) after inspection. It can be identified be JIC fitting.

Is JIC 37 or 45?

The JIC female has straight threads and a 37° flare seat. The Seal is made on the 37° flare seat. The SAE 45° flare male will mate with an SAE 45° flare female only. The SAE male has straight threads and a 45° flare seat.

What is an SAE 37?

JIC fittings (aka SAE 37° tube fittings, flared fittings, or SAE J514 fittings ) are the most popular hydraulic fluid connector in North America.

What thread is JIC?

JIC - Joint Industry Council Thread - SAE JIC 37°

Commonly referred to as just JIC fittings these metal to metal sealing type fittings have a 37° flare (sealing surface angle) and straight United National Fine straight Threads (UNF).

How is JIC measured?

Measure the thread diameter with an I.D./O.D. caliper. … Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections. Place the gauge on the threads until the fit is snug.

What are SAE threads used for?

SAE stands for the Society of Automotive Engineers. SAE fittings are mostly used in refrigeration, automotive piping systems and other low-pressure applications. It's common for copper tubes to be used with SAE threads. The SAE male and female halves both have a 45° flare seat.

What size is SAE 8?

dash 8 means 1/2" ID in hoses but means 1/2" OD on steel tubes. SAE can mean O-ring face seal or it can mean O-ring boss, or it can mean J.I.C. as well. In both J.I.C. and O-ring Boss, it will mean 3/4" fine threads, or 16 threads per inch.

Is SAE and UNF the same?

There are two general types of SAE bolts (sometimes referred to as machine screws). UNF (fine thread pitch) has more threads per inch than the same diameter bolt in the UNC (coarse thread pitch). Nut dimensions are maximums per SAE. Washer dimensions are for the regular size (vs.

What is SAE connection?

Society of Automotive Engineers (SAE) fittings are commonly used in refrigeration, automotive and low-pressure applications. These include: SAE O RING FLANGE – CODE 61 & CODE 62 SAE J518, ISO 6162.

How is SAE thread measured?

Use a thread pitch gauge to determine the number of threads per inch or the distance between threads in metric connections. Place the gauge on the threads until the fit is snug. Match the mea- surement to the charts. Measure the thread diameter with an I.D./ O.D.

What is the SAE International?

SAE International is a professional association and standards development organization for the engineering industry, with a special focus on transport sectors such as automotive, aerospace and commercial vehicles. The organization was originally established as the Society of Automotive Engineers.
